Walmart now offers contactless payment at all nine of its Hawaii stores, a small but welcome convenience for shoppers.

• Customers can now pay with a contactless card, phone, or smartwatch at checkout.
• All nine Hawaii Walmart locations have the feature live.
• Select Walmart and Sam's Club stores began rolling it out last month.
• Walmart had been a notable holdout on tap to pay, pushing its own Walmart Pay app instead.

Outlook: Walmart aims to have tap to pay working at all its locations by the end of the year.
